Exclusion Chromatography Gel Permeation Chromatography
, 1979In contrast to the separation techniques discussed up to now, separation by exclusion chromatography involves a single, unambiguous mechanism. In the absence of interactions (by definition) between the sample and the stationary phase surface, the elution order (or elution volume) is solely a function of the molecular size (see IX.B). Hence, this method

A technique using high pressure liquid chromatography gel filtration was used to evaluate GH-binding proteins (BP) in human plasma; eluate was monitored for radioactivity in a gamma-detection system connected to a computer.

Gel‐Filtration Chromatography [PDF]
Current Protocols in Molecular Biology, 1998 AbstractGel filtration (GF) chromatography separates proteins solely on the basis of molecular size. Separation is achieved using a porous matrix to which the molecules, for steric reasons, have different degrees of access‐‐i.e., smaller molecules have greater access and larger molecules are excluded from the matrix. Hence, proteins are eluted from the

Reproducibility of gel‐chromatography
International Journal of Peptide and Protein Research, 1984We think it worthwhile to other experimenters to mention the following observations. Recently it was noted that gel chromatographic separations of the five fragments resulting from the degradation of cytochrome c by bromocyanogen became dependent on the batch number of the gel. This dependency concerns only separations of unprotected fragments, using 7%

It is assumed that heparin is a heterogeneous substance. In order to further investigate the purification of heparin, a column chromatographic technique for the fractionation of heparin is described using various diameters of bead form cross-linked dextran gels and an automated apparatus. It was observed that Sephadex G-50 resulted in the separation of

SUMMARYCrude dialysed enzyme concentrates from several bulk honeys, comb honeys, and a ‘honey’ produced by sugar-feeding of caged bees, have been examined by chromatography on DEAE-cellulose, gel filtration through Sephadex G-200 and starch-gel ...
